Pecten testa ovato-orbiculari convexo-plana aequivalvi, lineis radiantibus confertis subaequalibus rectis, striis concentricis subtilissimis vix conspicuis, auriculis inaequalibus lineatis. — E montibus Westphalicis. M. M.
Eiförmig, flach-convex, gleichklappig, mit gedrängten, sehr zahlreichen, feinen und geraden ausstrahlenden Linien, von welchen einige hier und da etwas dicker erscheinen als die übrigen. Sie sind auch auf den ungleichen Ohren bemerklich und hier von deutlichen concentrischen Linien durchkreuzt, welche auf der übrigen Schale nur durch Vergrösserung sichtbar werden. — Kommt mit dem vorigen an demselben Fundorte vor.»

«2. AMENDED DIAGNOSIS
Distinguished from R. vagans and R. varians by thelarger number of radial striae and from the latter also by the smaller number of initial plicae. Distinguished from all other species of Radulopecten by the existence ol a non-plicate phase early in ontogeny.
3. AMENDED DESCRIPTION
Essentially very similar to R. varians. Differing in the maintenance of a sub-ovate form (text fig, 181) to the maximum height of 35 mm (BM unnumbered), in the somewhat higher convexity and slightly smaller byssal notch, in the tendency for the posterior auricles to meet the hinge line at 90°, and in the ornament.
Right valve ornamented with between 73 (MNO) and 110 (BM 23344) radial striae (PI. 10, Figs. 4, 5); left valve ornamented with between 60 (BM unnumbered) and 75 (MNO) and probably up to 85 (see Section 4) radial striae (PI. 10, Fig. 6) of which between 5 and 8 and possibly up to 12 (see Section 4) develop into low plicae bearing lamellae at intervals ol about 2 mm. H UA is plotted in text fig. 182. 4. DISCUSSION
The lectotype (herein designated) of 'Pecten' strictus MÜNSTER (BSPHG AS VII 636; PI. 10, Fig. 6) is a poorly preserved specimen but the existence of closely spaced radial striae leaves no doubt that it is a representative of the species described in Section 3, for wich MÜNSTER's name is thus the senior synonym. KILIAN and GUEBHARD's(1905) record ot unfigured examples of MÜNSTER's species from the Bathonian must be created with caution owing to the unusual stratigraphic horizon (see Section 5). COSSMANN (1907b) record of MÜNSTER's species is discussed under Chlamys (Ch.) textoria.»
